This section covers the engineering, design, fabrication, delivery and installation of main power transformers (MPT) and auxiliary power transformers (APT), as shown on the electrical one-line, Attachment I. The transformers shall be of the outdoor, oil-filled, self and forced air-cooled type dual 55/65 DEG. C rating with supplementary fan cooling. As an alternate to the 4.16kV-480/277 V oil-filled transformers, the Contractor may utilize an open, dry-type power transformer. The main step-up transformers shall be rated such that the top 55 DEG. C rating shall match the turbine-generator output at 30 DEG. C ambient and 0.85 power factor.
